IndiaBid
A pay-to-rank public leaderboard for India. Adding a listing is free — rank is
decided entirely by total amount paid, on a national board and separate city
boards. 10% of every rupee bid is pledged to underprivileged kids' education.
Stack
- Next.js (App Router), deployed on Vercel
- Supabase (Postgres) for the database
- Razorpay for payments (UPI, cards, netbanking)
Local development
npm install
npm run dev
Copy .env.local.example to .env.local and fill in the values described below.
Environment variables
| Variable | Where to get it |
|---|
NEXT_PUBLIC_SUPABASE_URL | Supabase → Project Settings → API |
NEXT_PUBLIC_SUPABASE_ANON_KEY | Supabase → Project Settings → API (publishable/anon key) |
SUPABASE_SERVICE_ROLE_KEY | Supabase → Project Settings → API (secret/service_role key — server-only, never expose to the browser) |
NEXT_PUBLIC_RAZORPAY_KEY_ID | Razorpay Dashboard → Settings → API Keys |
RAZORPAY_KEY_SECRET | Razorpay Dashboard → Settings → API Keys (server-only) |
RAZORPAY_WEBHOOK_SECRET | Razorpay Dashboard → Settings → Webhooks, once configured (see below) |
NEXT_PUBLIC_SITE_URL | Your deployed URL (e.g. https://your-app.vercel.app) |
Database
See supabase/README.md — migrations live in
supabase/migrations/ and are applied in order via the Supabase SQL Editor
(or supabase/apply_all.sql for a single-paste version).
Deploying
- Push this repo to GitHub.
- In Vercel, Import Project from that repo.
- Add all the environment variables above in Vercel's Project Settings →
Environment Variables, using your production Supabase project and
Razorpay live keys when you're ready to go live (keep using test keys
until then).
- Once deployed, set
NEXT_PUBLIC_SITE_URL to the real deployed URL and
redeploy.
- In the Razorpay Dashboard, add a webhook pointing at
https://<your-domain>/api/razorpay/webhook, subscribed to the
payment.captured event, and put its signing secret into
RAZORPAY_WEBHOOK_SECRET. This is the reliable path that updates the
leaderboard even if a buyer closes their browser right after paying — it
can't be tested from localhost since Razorpay needs a public URL to call.
